MAINTENANCE SECTION
6.
Insert the assembled Bevel Pinion, gear end trailing,
into the unthreaded end of the Bevel Pinion Housing.
Move the assembly through the Bearings in the Hous-
ing until the Thrust Washer stops against the end face.
7.
Install the Pinion Clamp Washer (412), concave end
(dish end) trailing, onto the shaft of the Bevel Pinion.
8.
Install one of the Rear Bearing Thrust Washers (411)
on the shaft against the Clamp Washer.
9.
Apply Ingersoll–Rand No. 67 Grease to both sides of
the Pinion Rear Thrust Bearing (410) and slide the
Bearing followed by the remaining Rear Bearing
Thrust Washer onto the shaft of the Bevel Pinion
against the installed Washer.
10. While compressing the Bearing and Thrust Washers
against the Pinion Clamp Washer, use snap ring pliers
to install the Thrust Washer Retaining Ring (413) in
the annular groove around the shaft of the Bevel
Pinion.
11. If the Socket Retainer Pin (418) was removed from
the Spindle (417), insert the smaller shaft of the Pin
into the larger opening in the Spindle allowing the
Pin to protrude out of the Spindle.
12. Insert the Socket Retainer Pin Spring (419) in the
hole against the Pin.
13. Position the Socket Retainer Expansion Plug (420),
concave end leading, against the Spring. Use a punch
to compress the assembly into the hole until the Plug
bottoms on the surface inside the Spindle. When the
Plug bottoms out, sharply rap the punch with a ham-
mer to expand the Plug and capture the assembly.
14. Lubricate the Spindle Lower Bearing (421) with
Ingersoll–Rand No. 67 Grease and using a piece of
tubing that contacts the outer ring of the Bearing,
press the Bearing into the large opening of the
Spindle Lower Bearing Cap (422).
15. Insert the Spindle, square drive end trailing, through
the Bearing Cap and Bearing and install the Bevel
Gear (414) on the shaft of the Spindle.
16. Install the Bevel Gear Washer (415), followed by the
Bevel Gear Nut (416) against the Gear on the shaft of
the Spindle. Using a 7/8” socket, tighten the Nut to
100 ft–lbs. (136 Nm) torque.
17. Apply a thin coat of lubricant to the inner surface of
the hole in the Angle Housing where the Bevel Pinion
Housing is inserted.
18. Start the assembled Bevel Pinion Assembly, gear end
leading, into the Angle Housing until the threads on
the Bevel Pinion Housing start to engage the threads
in the Angle Housing.
19. To prevent the Angle Housing from rotating, place
the Angle Housing, spindle opening upward, in par-
tially open vise jaws.
20. Looking downward into the opening, a slot in the
Housing will be visible between the outer surface of
the Spindle Upper Bearing and the leading edge of
the Bevel Pinion. Position a 0.245” thick gage–block
(or equivalent measuring device) in the slot against
the cage of the Bearing.
21. Thread the Bevel Pinion Assembly into the Housing
until the leading edge of the Bevel Pinion contacts the
gage–block.
22. There are holes in the groove for the Coupling Nut
Retaining Ring (424) nearest the pinion end of the
Housing. There are also slots to the outer edge of the
Bevel Pinion Housing. Remove the gage–block and
align the closest hole and slot combination. Insert the
Pinion Housing Alignment Ball (404) into that hole
and slot.
23. Hold the Housing with the Ball at the twelve o’clock
position and slide the Coupling Nut (423), threaded
end trailing, onto the Angle Housing.
24. Spread one of the Coupling Nut Retaining Rings and
install it in the groove to capture the Ball. Install the
other Retaining Ring in the remaining groove.
25. Inject Ingersoll–Rand No. 67 Grease into the Spindle
Upper Bearing until it is filled to about forty percent
of its capacity.
26. Make certain that the leading end of the spindle shaft
enters the Spindle Upper Bearing and insert the
assembled Spindle into the Angle Housing.
27. Using a spanner wrench, thread the Bearing Cap into
the Angle Housing until the Spindle starts to bind.
When the Spindle begins to bind, back the Bearing
Cap outward 1/8 of a turn (approximately 45 de-
grees).
28. Look into the opening for the Bearing Cap Retaining
Ball (402) to determine that the groove in the Cap
aligns with the hole for the Ball. Move the Bearing
Cap in or out until they are aligned and the Spindle
rotates freely.
29. When they are aligned, insert the Ball into the hole.
30. Apply a quality thread–locking compound to the
threads of the Ball Retaining Screw (403) and thread
the Screw into the Housing. Make certain the
Spindle rotates freely before the compound sets up.
31. Reinstall the Angle Head on the tool.
